Definitions

  • the invention relates to a hearing aid, in particular a behind-the-ear hearing aid with a receiver and a connector. Furthermore, the invention relates to a method for mounting a hearing aid, in particular a behind-the-ear hearing aid.
  • Hearing devices generally have a housing in which a microphone, an amplifier device, a receiver and a power supply, usually a zinc-air battery, are arranged.
  • the handset is connected to an acoustic output of the housing to output the acoustic signals processed and generated by the hearing aid.
  • BTE hearing aids Behind the ear portable hearing aids (hereinafter referred to as BTE hearing aids) are usually held by a carrying hook behind the ear of a hearing aid wearer.
  • the carrying hook In addition to the holder of the BTE hearing aid, the carrying hook usually fulfills another function.
  • the carrying hook is traversed by a sound conductor, through which the sound generated by the earpiece of the BTE hearing device is transported to a sound tube connected to the front end of the carrying hook and forwarded by the earpiece into an auditory canal of the hearing device wearer.
  • the carrying hook consists of a bent titanium tube which is partially encapsulated by a plastic material.
  • This Titanium Tube is routed through the earhook inside the BTE Hearing Aid to the front of the Carrying Hook. For a fastening of the titanium tube in the housing of the BTE, this has in a region between the actual housing of the BTE hearing aid and the carrying hook a plastic retaining tab, by means of which the titanium tube is fixed on / in the BTE hearing aid.
  • Such a hearing aid may have a slim design in the transition region between the housing of the BTE hearing aid and the carrying hook, but it is always necessary to open the housing of the hearing aid for replacement of the carrying hook. Furthermore, a screw connection of the carrying hook to the housing of the BTE hearing aid is not feasible.
  • BTE hearing aids are known with a metal fitting for a carrying hook, which have a thread on a front, on the housing of the BTE hearing aid protruding portion. On the thread of the carrying hook can be screwed, which allows a simple replacement of the carrying hook in case of repair.
  • the connector has an integral sound conduit, which opens into the receiver of the hearing aid.
  • BTE hearing aids By adapting the BTE hearing aids to different hearing damage, z. B. due to different levels of performance, as well as for cosmetic reasons and also to increase the wearing comfort, as small as possible and small housing designs are preferred in BTE hearing aids.
  • the curvatures in a range of different BTE hearing aids change, on which the carrying hook can be provided. Therefore, different metal fittings are required for different BTE hearing aids, because there is a fixed angle between a terminal area for the carrying hook and the sound conduit of the metal terminal, which depends on the particular curvature within a specific BTE hearing aid.
  • the DE 10 2006 004 033 A1 discloses a BTE hearing aid, in particular a micro-size high-end hearing aid, with an insertable into an inner ear earmold.
  • the BTE hearing aid is acoustically connected thereto by means of a sound tube via a sound tube fastening element of the otoplastic.
  • the sound tube is so connected to the BTE hearing aid that it can be quickly and easily replaced.
  • the object of the invention is achieved by means of a hearing aid, in particular by means of a BTE hearing aid, according to claim 1 and by a method for (pre) mounting a hearing aid, in particular a BTE hearing aid, according to claim 15.
  • the bridging connector is preferably designed as a, at least in a longitudinal center section flexible, sound tube; d. H. the longitudinal center section of the sound tube is flexible in a direction perpendicular to its longitudinal direction.
  • the sound signal generated by the hearing aid of the hearing aid is transported via the sound tube, which is bendable at least in the longitudinal center section, to the standardized connecting piece, wherein the connecting piece is fixedly connected to a housing of the hearing aid.
  • a carrying hook can be releasably attached.
  • An inventive method for (pre) mounting a hearing aid is carried out such that first a longitudinal end portion of the sound tube is mounted on the connector or the handset of the hearing aid. Subsequently, the this longitudinal end portion opposite longitudinal end portion of the sound tube is attached to the handset or on the connector, wherein the handset and / or connector can already be mounted in the housing of the hearing aid. Depending on whether no, one or both components (receiver, connector) are already installed in the hearing aid, the sound tube in accordance with the invention mounting method is bent or bent accordingly.
  • connection piece is produced, and the different angle with different hearing aid devices is compensated or bridged by the sound tube.
  • the sound tube over its entire extension in a longitudinal direction, in particular in a direction perpendicular to its longitudinal direction, formed flexible or flexible.
  • the sound tube is continuously bendable along its entire longitudinal extension in a direction perpendicular thereto. Ie. within the hearing aid, the sound tube is then recorded kink-free, which can be the sound signal from the handset to the connector well, lossless and possible low-reflection transport.
  • the sound tube is elastically deformable such that by means of this elastic deformability of the angle between the mounting position of the connector and the mounting position of the listener can be bridged. Furthermore, this can also be done by a plastic deformability of the hose. In this case, it is particularly preferred that this plastic deformability can be reversed again in such a way that the sound tube can be brought back into its original position or its original configuration. Ie. the sound tube is in such embodiments of the invention as possible reversibly plastically deformable.
  • the sound tube when bridging the distance between the receiver and the connection piece, ie in its curved position, maintains essentially the same cross-section with respect to a non-bent position substantially in all cross-sections.
  • This relates in particular to inner, preferably circular, configured cross sections of the sound tube through which the sound signal passes.
  • the sound tube has a mesh, preferably a wire mesh, which gives the sound tube a certain (cross-sectional) stability.
  • a flexibility of the sound tube can be influenced. If the braid is plastically deformed, then preferably the sound tube is plastically deformed. The same applies to an elastic deformation of the braid.
  • At least the front portion of the connecting piece according to the invention which preferably has a screw connection for the carrying hook, is made of a metal or a metal alloy.
  • the entire connector according to the invention is formed from metal or a metal alloy.
  • the sound tube according to the invention between the connector according to the invention and the receiver of the hearing aid is preferably made of a plastic.
  • the sound tube can be bent at any angle and thus universally applicable in any hearing aid.
  • the flexible plastic sound tube is simply placed on / in the connector and thereby fixed, and then bent depending on the angle to the listener and also fixed there. Of course, this can be reversed kinematically; ie the plastic sound tube can first be placed on / in the receiver and thereby fixed and then attached only with the connector.
  • a respective installation of the sound tube on / in the connector or on / in the handset can be done via a plug and / or an adhesive connection. It is possible to put the sound tube on a projection of the connector and / or a projection of the listener; conversely, it is of course possible to insert the sound tube in a recess in the connector and / or a recess in the handset. A mixed form of fortifications is of course also applicable.
  • the material connector integrally formed in the prior art metal connector can only a single angle between the mounting position of the metal connector and the mounting position of the listener. According to the invention, this angle is not limited to a single one by the use of the plastic sound tube, but with the plastic sound tube according to the invention a plurality of angles can be bridged accordingly, ie desired angles can be laid according to the invention without problems. It is therefore necessary for almost all hearing aids of a type or series only a standardized connector and the flexible plastic sound tube, both of which can be used in all hearing aids. A single adaptation is possibly still necessary at a length of the plastic sound tube.
  • BTE hearing aid worn behind the ear - hereinafter referred to as BTE hearing aid.
  • the invention should not be limited only to such BTE hearing aids, but quite generally applicable to hearing aid devices; So also devices affect that not only serve to improve a hearing impairment, but are also suitable hearing a Höragistechnikloss in an acoustically difficult situation - such. B. on a construction site - to improve. This concerns z. As a hearing protection with integrated radio.

As a thread can be provided, by means of which the BTE hearing aid 1 and the support hook 40 can be easily connected to each other. It is therefore not possible, a releasable connection of the support hook 40 in the transition region to create the housing 2 of the BTE hearing aid 1. For replacement of the carrying hook 40, the housing 2 of the BTE hearing aid 1 must be opened. Furthermore, in such an embodiment, the carrying hook 40 is completely traversed by the titanium tube 42, which prevents a transparent embodiment of the carrying hook 40.
